SysUtils.Now is local not UTC. DateTimeToUnix cannot distinguish if
passed parameter is UTC or local. There would need to be NowToUnix()
which takes Now in UTC and converts to Unix Time.

$ date +"%z %Z"
+0100 CET
$ LC_ALL=C; date -s"1970-01-01 00:00:00 +0000" -R; echo -n "Date: ";
date +%s; /tmp/project1
Thu, 01 Jan 1970 01:00:00 +0100
Date: 0
DateTimeToUnix(Now): 3600
